About Converting Technical atmospheres to KSI
Technical atmosphere and KSI both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Technical atmosphere is kilogram-force per square centimeter, and kips per square inch.
Formula
ksi = technical atmospheres × 0.0142233433071
This factor comes from each unit's defined relationship to the category's base unit: 1 technical atmosphere equals 98066.5 base units, and 1 ksi equals 6894757.29317 base units, so dividing one by the other gives the direct technical atmosphere-to-ksi factor of 0.0142233433071.
Simple example
1 at × 0.01422334331 = 0.0142233433 ksi
1 technical atmosphere = 0.0142233433 ksi.
Real-world example
100 at × 0.01422334331 = 1.422334331 ksi
100 technical atmospheres = 1.422334331 ksi.

Frequently asked questions
How many ksi are in 1 technical atmosphere?
1 technical atmosphere equals 0.0142233433 ksi, using the exact defined conversion factor rather than an estimate.
How do I convert technical atmosphere to ksi?
Multiply the technical atmosphere value by 0.01422334331. The converter above does this instantly to whatever precision you set.
How do I convert ksi back to technical atmosphere?
Use the reverse factor: 1 ksi equals 70.30695796 technical atmospheres. You can also use the swap control in the converter above to flip the direction instantly.
What is a technical atmosphere?
Technical atmosphere (at) is a unit of engineering.
What is a ksi?
KSI (ksi) is a unit of engineering.
Is the technical atmosphere to ksi conversion exact?
Yes. Both technical atmosphere and ksi are defined by fixed standards rather than physical artifacts, so the factor of 0.01422334331 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
